Problem Type 1: MOI Calculation Strategy: Identify standard shape, use parallel/perpendicular axis theorems. For composite bodies, add/subtract MOI of components.

Problem Type 2: Rolling on Incline Strategy: Use energy conservation for speed. Use a = g*sin(theta)/(1+k^2/R^2) for acceleration. Compare bodies by k^2/R^2 ratio.

Problem Type 3: Angular Momentum Conservation Strategy: Identify that external torque is zero. Set I_1omega_1 = I_2omega_2. Calculate energy change separately.

Problem Type 4: Hinged Rod Released from Horizontal Strategy: Use energy conservation for omega. Apply centripetal + tangential force analysis at the desired position.

Problem Type 5: Sliding to Rolling Transition Strategy: Friction decelerates translation and accelerates rotation until v = R*omega. For a solid sphere: v_final = 5v_0/7.
